Description

This invention relates to a vehicle for manipulating the shape of a rotor blade for manufacturing a rotor blade of a wind turbine. The invention further relates to a manipulation device that includes such a vehicle. In addition, this invention relates to a method for manufacturing a rotor blade of a wind power installation.

Wind turbines are generally known and generally require at least one, in most cases three rotor blades, which must be driven by wind. Modern wind power plants, one of which, for example, is shown in FIG. 1, they can have an estimated power of several megawatts (MW) and, for this, need large rotor blades, respectively. Such rotor blades can already have a length of about 50 m or more. Moreover, such a rotor blade is often, at least in a large area, made of fiberglass reinforced polymer or a similar material. Moreover, the generally accepted manufacturing option is to produce a rotor blade or a portion of a rotor blade from two parts of the casing. First, both parts of the shell are made essentially separately and then superimposed on each other. For the manufacture of such a part of the casing, the shape of the rotor blade is used, which defines in particular the shape of the manufactured rotor blade or the corresponding portion of the rotor blade. Here, for example, fibrous connective tissues can be laid, which are then impregnated with the corresponding polymer. The impregnation with the polymer can be carried out, for example, in such a way that the fibrous tissue is tightly enclosed in an airtight space, and then, under reduced pressure, in most cases similar to vacuum, is introduced into this airtight space, that is, the corresponding polymer is sucked.

Accordingly, such shapes of the rotor blade are sized in order of magnitude of the manufactured rotor blade or the manufactured portion of the rotor blade and, accordingly, can have a length of, for example, about 50 m and a width of about 5 m. At the latest, when two separately made shell parts are to be connected, at least one of the forms of the rotor blade must be moved to the assembly shop in which the manufacture of the rotor blade takes place. In order to optimize production processes in such an assembly workshop, it may be preferable that various manufacturing operations are carried out at various locations. This requires further movement of the shapes of the rotor blades in the assembly shop.

The movement of large, as well as impractical due to their size cargo at industrial industrial enterprises, in principle, is known. For example, for this, large and powerful are used, most often adapted for a special case of using trolleys with a lifting device, which can move on a flat, flat surface of the floor of the assembly shop. In this case, due to the very even and horizontal execution of such a floor of the workshop with high accuracy, such trolleys with a lifting device can move at relatively low energy costs.

However, directly for objects that are impractical due to their size, such as, for example, such a long shape of the rotor blade, this method is difficult, and care must be taken to ensure that when moving the shape of the rotor blade does not collide with an object in the assembly shop by mistake. In addition, the connection of such a trolley with a lifting device also implies the appropriate quality of the floor of the workshop and thorough cleaning of the floor of the workshop in order to ensure the movement of the trolley with the lifting device.

Thus, such well-known solutions are still associated with high costs and require a staff with extensive experience and a high level of vigilance during maintenance.

Thus, the basis of this invention is the task of solving at least one of the above problems. In particular, the manipulation of rotor blade shapes should be improved. At the very least, an alternative solution should be proposed.

The invention provides a vehicle according to claim 1. This vehicle is prepared for manipulating the shape of a rotor blade for manufacturing a rotor blade of a wind power plant or for manufacturing a portion of a shell of a rotor blade of a wind power plant. In particular, the vehicle supports the shape of the rotor blade, which may be, for example, 48 m long, and / or the vehicle may be 48 m long. The vehicle is prepared for use in a handling device, which may, in particular, be part of an assembly workshop.

Such a handling device includes a first rail kit for moving a vehicle in a first direction and a second rail kit for moving a vehicle in a second direction. Here, two directions should be understood as two directions located at an angle to each other, that is, not only the forward and reverse directions. Moreover, the rail set includes at least two parallel rail tracks. However, for each rail set, three or more parallel tracks may also be provided. Also, the first and second rail sets may in each case have a different number of parallel rail tracks. Preferably, the first or second direction is the longitudinal direction of the vehicle, and accordingly, the second or first direction is the transverse direction of the vehicle. Moreover, in the longitudinal direction, a rail set is preferably used with fewer rail tracks than in the transverse direction. For example, in the transverse direction, four rail tracks can be provided next to each other, so that it is therefore possible to better distribute the weight of the vehicle onto the rails across the width of the vehicle.

In this case, the vehicle includes a first wheel set having several wheels for moving along the first rail set and a second wheel set having several wheels for moving along the second rail set. Thus, as a result of this, conditions are created for the vehicle to be moved and thus the shape of the rotor blade in two different directions, and using the rail, directional transport is possible, which prevents possible collisions with other stationary objects in the vicinity of the vehicle. Thus, by using the appropriate wheel set for the corresponding rail set, it is proposed to use the corresponding wheel set in each direction. Thus, a change of direction can be carried out by changing the wheel set. Accordingly, the use of rail arrows to change one rail set to another is prevented.

Preferably, the vehicle has a switching device for switching from the first wheel set to move along the first rail set to the second wheel set to move along the second rail set. Thus, the vehicle, for example, in the first direction can move to the point of intersection of the first rail set with the second rail set. Then there is used a switching device in order to switch from the first wheel set to the second wheel set. Needless to say, it is also possible to switch back from the second wheel set to the first wheel set.

Accordingly, such a switch from the first wheel set to the second wheel set is carried out in such a way that the first wheel set previously moved along the first rail set, and now, after switching to the second wheel set, this second wheel set rests on the second rail set, and thus the vehicle can now move around the second rail set.

It is preferable to perform the vehicle in such a way that the shift device is prepared for raising and lowering the wheels of the first wheel set, the wheels of the first wheel set being able to move from the lowered position to the raised position and vice versa. By lowering the wheels of the first wheel set, the vehicle rises. Thus, in principle, there are two positions, namely, the lowered position in which the first wheel set according to the purpose is completely lowered, and the raised position in which the first wheel set according to the purpose is fully raised. In the down position, the vehicle loads the first rail set with the wheels of the first wheel set, and the wheels of the second wheel set are higher than the wheels of the first wheel set and at least no longer load the second rail set. In the raised position, everything is exactly the opposite, and the vehicle loads the second rail set with the wheels of the second wheel set, and the wheels of the first wheel set no longer load the first rail set.

This means that when lowering the wheels of the first wheel set, the switching device moves them down onto the rails of the first rail set so that as a result the whole vehicle rises except for the wheels of the first wheel set and part of the switching device, as well as objects mounted on the vehicle are raised , such as the shape of the rotor blade, as well as, if necessary, the immersed elements of the manufactured rotor blade. In this case, considerable efforts should be made, in particular depending on the weight of the equipped vehicle and depending on the number of wheels of the first wheel set, which are affected by the switching device.

Thanks to the use of the rail system, that is, to the use of the first rail set and the second rail set, the dimensions of the individual elements, in particular the necessary heights for the active wheel set in each case, can be set with relatively small tolerances. Thus, when switching from the second wheel set to the first wheel set by lowering the first wheel set, a slight lifting height may suffice. Although the required lifting force when lowering the wheels of the first wheel set is large, nevertheless, the necessary lifting work due to the low lifting height can remain relatively small.

Thus, it is also preferably proposed that the switching device lowers and / or raises the wheels of the first wheel set using a lever-knee mechanism. Such a lever-knee mechanism is characterized in that - like the human knee, which gave the name to this mechanism - due to the angles used, straightening can be achieved with excessive force, but with a slight stroke. Thus, for the proposed application in the switching device, namely for the power lowering of the wheels of the first wheel set with a small stroke, such a lever-knee mechanism can preferably be used. In addition, the rectified state, in which the wheels of the first wheel set are lowered and absorb the entire load of the vehicle, can be maintained with little effort or even without effort.

Preferably, the switching device is hydraulically and / or electrically actuated. Thanks to the hydraulic drive, excessive forces are possible at the same time with high-precision movement. The same can be achieved by means of an electric drive, if necessary with an appropriate gear ratio. However, an electric drive is preferably provided to create hydraulic pressure. In this case, the switching device operates hydraulically if it is driven by electrically driven pumps, and also preferably by electrically controlled valves.

According to one embodiment of the invention, it is proposed that the switching device for each wheel of the first wheel set includes lifting means, in particular using a lever-knee mechanism, for raising and lowering the corresponding wheel, the lifting means being preferably synchronously controlled. As a result of this, the necessary effort, which, being divided - with a uniform distribution - by the number of lifting means, is formed, ultimately, precisely from the weight of the equipped vehicle, can be divided and thereby reduced for each individual lifting device. In particular, this occurs with uniform distribution and synchronous control, in which, in the optimal case, all the wheels of the first wheel set must simultaneously reach the rails of the first rail set and then take the forces acting so far on the wheels of the second wheel set. The vehicle may also be configured such that the wheels of the first or second wheel set are grouped. For example, wheels can be grouped in pairs or four wheels per group. In this case, it is proposed to provide lifting means for each such group of wheels.

Preferably, the switching device is supplied with electrical energy from an electric, rechargeable energy storage device. In particular, such an electrical energy storage device may be a battery storage device, i.e. a storage device consisting of one or more rechargeable batteries, which may also be referred to as batteries. Consequently, it is possible to control the switching device, in particular the aforementioned lifting means on the vehicle, without the vehicle having to be connected to the corresponding supply line during such a switching process. In particular, such a change in direction, in which the switching device is also actuated, occurs in the region of intersection between the two rail sets and thereby is most often not in the working position. Thus, an electric, rechargeable energy storage device is preferably provided on the vehicle.

A coupling is preferably provided in order to connect the vehicle and / or the shape of the rotor blade mounted on the vehicle with the power lines, compressed air, vacuum and / or control data. Such a coupling makes it possible to move the vehicle without connecting (docking) with the corresponding supply lines, so that the connection should only be established in the operating positions necessary in each case. Thanks to such a coupling, an electric energy storage device can also be recharged to supply the switching device. The docking itself is also carried out using an electric drive, which is supplied from the vehicle’s battery.

According to one embodiment of the invention, it is proposed that several wheels are driven by a common drive motor, and that the drive is driven by drive shafts and cardan joints. In particular, it is proposed for driving in the longitudinal direction. For driving in the transverse direction, each drive wheel set has its own drive, according to at least one embodiment. Thus, the common drive motor drives at least two, preferably four drive shafts, which in each case are connected to at least one wheel by means of a universal joint. Thus, it is sufficient to provide a single drive motor for several wheels. The drive torque can be distributed through the drive shafts through the vehicle and transmitted to the respective wheels to bring them into motion. Since the vehicle is preferably provided for moving along straight, non-bent rail sets in each case, the wheels of at least one wheel set, which thus must in each case be rolled along the same rail set, can be driven in motion synchronously. In addition, thanks to the rail system, in principle, it is possible to count on the same rolling properties for all wheels of the wheel set in the absence of damage.

Preferably, at least one cardan joint is located in each case at the end of the power transmission, namely in this way between the drive shaft and the wheel driven in each case. In particular, it is preferable for the wheels of the first wheel set, which can be raised or lowered. Thanks to the cardan joint and in particular the long drive shaft, the corresponding power transmission can remain independent or little dependent on raising or lowering the corresponding degree.

Preferably, a gear mechanism is provided between the cardan joint and the wheel in order to reduce a large number of revolutions of the drive shaft to a more insignificant number of revolutions of the wheel. Accordingly, the same gears should be provided for each drive wheel of the wheel set, at least in terms of gear ratio. Thus, using a common drive, synchronous wheel travel can be achieved. For the described driving in the longitudinal direction, this synchronous stroke is achieved by mechanics. The driving can be carried out by means of a high-speed drive motor, and the use in each case of one gear mechanism on each wheel driven in motion makes it possible to use gears calculated weaker. In addition, a large number of revolutions of the drive shafts is also achieved by transmission only directly on the wheel, and thus the corresponding drive torque to these faster rotating drive shafts can be kept small, which can lead to a correspondingly lower weight design of both the drive motor and the drive shafts. As a consequence, the weight of the entire vehicle can accordingly be kept light. For the described transverse driving, the individual drives are electrically connected and synchronized.

Preferably, the drive motor is powered by electricity and is supplied with electric power from one or more electric battery storage devices that are present in the vehicle.

In addition, according to the invention, there is provided a manipulating device for manipulating the shape of a rotor blade for manufacturing a rotor blade of a wind power plant or a part of a shell of a rotor blade of a wind power plant, wherein the manipulating device includes a vehicle according to at least one of the above-described embodiments, the first rail a kit for moving a vehicle in a first direction and a second rail kit for moving a vehicle Islands in the second direction. The effects, advantages and manipulation methods result from the description above for a vehicle according to at least one of the described embodiments.

Preferably, the first rail set is oriented substantially in the longitudinal direction, and thereby transverse to the second rail set, in order to allow the vehicle to move substantially in two transverse directions. In particular, the handling device, that is, both rail sets, as well as the vehicle, is designed so that the vehicle can move in the longitudinal direction and in the transverse direction.

Preferably, the first rail set and / or the second rail set have round rails embedded in the floor (workshop). In particular, the first rail set and / or the second rail set in each case are formed from such round rails embedded in the floor. In this case, the rails are embedded in the floor in such a way that in a view with a cut extending across the longitudinal direction of the respective rails, a semicircle or a smaller part of the round rail protrudes above the floor. Thus, a rail system is created in which only a semicircular rib or a smaller part protrudes from the floor. Preferably, the respective wheels, i.e. the wheels of the first wheel set or the wheels of the second wheel set, are adapted to this convex bend. Thus, the vehicle with its adapted wheels can be rolled on rails, in particular on the floor rails of the assembly shop, at the same time these rails can practically not protrude from the floor, and additional non-moving rails vehicles can cross these rails. Also, for people who move near the rails, in particular they cross, there is less chance of injury. In particular, the risk of someone tripping on the rails is reduced.

According to an embodiment of the invention, it is proposed that the manipulating device includes a first rotor blade shape for manufacturing a first portion of a rotor blade shell and, furthermore, a second rotor blade shape arranged on a vehicle for manufacturing a second rotor blade shell portion. The first shape of the rotor blade may be stationary, or it may also be located on the vehicle, which may correspond to the above-described embodiment of the vehicle or may have a different design.

In addition, a hinge device is provided that is prepared to rotate the second shape of the rotor blade, namely, prepared in such a way that the second part of the shell of the rotor blade installed in the second shape of the rotor blade rotates on the first part of the shell of the rotor blade installed in the first shape of the rotor blade, so as to connect these two parts of the shell of the rotor blade and to produce the rotor blade or to produce the corresponding section of the rotor blade.

Preferably, the hinge device is prepared in order to be connected rigidly, but with the possibility of disconnection with the second form of the rotor blade for rotation. For this purpose, for example, fastening means are provided, which are part of the rotary device and have a retractable cylinder, which in each case can be inserted into the corresponding receiving element on the shape of a rotor blade. Additionally, fixation may be provided so that one, in particular several, strong joints are established between the rotary device and the corresponding shape of the rotor blade. These connections are so rigid that the second shape of the rotor blade can now be rotated by means of a rotary device, in particular rotated around an approximately horizontal axis of rotation, and in particular approximately 180 degrees around this horizontal axis of rotation, without being disconnected from the rotary device. Later, in particular, when the shape of the rotor blade was again folded back and mounted on the vehicle again, this connection can be disconnected again due to the locking being disconnected, and the example cylinder mentioned again exits the receiving element.

The invention also provides a method for manufacturing a rotor blade, which includes the following steps:

- moving the second form of the rotor blades using a vehicle in the first direction in close proximity to the hinge device,

- moving the second form of the rotor blades using the vehicle in the second direction to the hinge device,

- the connection of the second form of the rotor blade with the hinge device, in particular, so that the hinge device during the first essentially vertical movement is moved to at least one receiving element of the second shape of the rotor blade in the connection position, and that in this connection position fixation is made, and

- rotation of the second shape of the rotor blade using a hinge device, in particular around a substantially horizontal axis, until the second part of the shell is on the first part of the shell installed in the first form of the rotor blade in order to connect both parts in this position rotor blade shells for manufacturing a rotor blade.

In accordance with this, the shape of the rotor blade is first moved by the vehicle in the first direction in close proximity to the hinge device. In particular, this movement is a movement in the longitudinal direction of the vehicle, which is also a movement essentially in the longitudinal direction of the manufactured rotor blade. In this case, the second form of the rotor blade can move here from the previous working position.

Then, the second shape of the rotor blade by means of the vehicle moves in the second direction, in particular in the transverse direction, to the hinge device. Now the shape of the rotor blade is located within reach for fixing with the hinge device, and accordingly, the method proposes to connect the second shape of the rotor blade with the hinge device, in particular to connect so that the hinge device during the first essentially vertical movement is moved at least one receiving element of the second shape of the rotor blade in the connection position, and that in this connection position is fixed. This fixation can also be carried out in such a way that the movement that the hinge device performed for the connection, at first cannot be carried out in the opposite direction by itself, and the thus connected shape of the rotor blade cannot also leave the connection.

Preferably, the shape of the rotor blade is lifted from the trolley by means of a hydraulic cylinder and hung on the power loops, then lowered again and fixed on the power loops.

Finally, the second shape of the rotor blade is rotated by a hinge device, in particular around a substantially horizontal axis, until the second part of the shell, which is laid in the second shape of the rotor blade, is on the first part of the shell installed in the first shape of the rotor blade. It is provided that these two parts of the casing are arranged on top of each other so that in this position both parts of the casing of the rotor blade can be connected to make the rotor blade. In particular, both parts of the casing can be glued at the corresponding contact edge.

Preferably, a vehicle is used according to one of the above embodiments, and / or a manipulation device according to one of the above embodiments is used. By way of example, the invention is now explained further by way of exemplary embodiments, with reference to the accompanying drawings. In the drawings:

FIG. 1 schematically shows in a perspective view in a longitudinal direction a vehicle with a holder for the shape of a rotor blade and an articulated device;

FIG. 2 shows a top view of a vehicle without a mold holder and without the shape of a rotor blade;

FIG. 3 shows essentially the vehicle of FIG. 2 in perspective view;

FIG. 4 shows a vehicle in a front view in a longitudinal direction;

FIG. 5 shows a partial sectional view of a vehicle indexing device with a fragment of a vehicle;

FIG. 6 shows a fragment of a vehicle in perspective view; and

FIG. Figures 7 and 8 show, in partial section in the longitudinal direction, a fragment of the vehicle in various positions for illustrating the raising and lowering of the wheel unit.

FIG. 1 shows a perspective view of a vehicle 1 with a lattice truss located on it 2. The lattice truss 2 is already roughly adapted to the shape of the rotor blade being manufactured and is provided for setting the shape of the rotor blade. In accordance with the purpose, such a shape of the rotor blade according to the image shown is placed on top of this trellised truss or superimposed on it. In the case shown, the provided shape of the rotor blade is provided for manufacturing a portion of the shell of the rotor blade. The further shape of the rotor blade for the further part of the casing would have to fit into the one shown in FIG. 1 only partially trellised truss 2 '. Ultimately, the manufactured rotor blade is assembled essentially from these two parts of the shell. For simplicity, a trellised truss, such as trellised truss 2, may also be referred to as a mold holder.

In order to connect both parts of the rotor blade shell thus manufactured, a hinge device 50 is provided which has a fixed arm 52 and a movable arm 54. The movable arm 54 can rotate around the pivot axis 56 with respect to the stationary arm 52 so as to thereby rotate holder 2 forms on holder 2 'forms. Moreover, according to the image of FIG. 1, the mold holder 2 is substantially rotated and is put on top of the mold holder 2 ′.

To this end, the mold holder 2 is fixed to the movable arm 54 by means of the spirit of the fastening elements 58, and additionally, fixing is provided in order to ensure connection also during the turning process. Accordingly, by turning the movable arm 54, the entire mold holder 2, including the stacked shape of the rotor blade, can be rotated onto a further mold holder 2 ′ in order to connect both of these parts of the rotor blade shape. Cones are provided for contacting the mold holder 2 with the vehicle 1, which are arranged substantially vertically in order to mount the mold holder if it is pivoted again from the further mold holder 2 ′. For this, the cone-shaped receiving elements on the vehicle 1 can interact with the cone-shaped pins on the mold holder 2 or vice versa.

In addition, in FIG. 1 you can see part of the first wheel set 10 and part of the second wheel set 20. In this case, from the first and second wheel set 10 and 20, respectively, in each case only one pair of 12 and 22 wheels is shown. In this case, the first wheel set 10 is provided for moving the vehicle 1 in the longitudinal direction, namely in the longitudinal direction of the manufactured rotor blade. This approximately corresponds to the direction in the plane of the drawing. To move in the longitudinal direction, there are several rails of the first rail set, of which one rail 14 of this first rail set is shown embedded in the floor 30. Moreover, the rail 14 is made in the form of a round rod and in this form is embedded in the floor 30. You can see that a pair of 12 wheels of the first wheel set 10 does not touch either the floor 30 or the rail 14. In contrast, the first wheel set 10 is raised from the floor 30 and the first rail set. In this case, the vehicle 1 is also shown with an offset in the direction that extends across the passage of the rail 14, so that the pair of 12 wheels is not located directly above the rail 14, but with an offset from it. From a pair of wheels 12, a part of the wheel 13 can be seen. This wheel 13 is adapted from the point of view of its shape to roll along the rail 14. In this regard, the wheel 13 has a concave surface that is essentially adapted to the shape of the rail 14, namely the round to the core.

For driving, a drive shaft 16 is provided, which is connected to the wheel set 10 of the wheels by means of a cardan joint 18, in order to drive at least the wheel 13. The first wheel set 10 of the vehicle 1 includes several pairs of wheels, namely, twenty-four pairs of wheels similar to a pair of 12 wheels, of which, however, not all have a drive. However, depending on the requirements, it is also possible to drive more or less pairs of wheels or, in particular, all pairs of wheels of the first wheel set 10.

A pair of 12 wheels of the first wheel set 10 is rigidly connected to the vehicle 1. Shown in FIG. 1, the situation is that the first wheel set 10 and with it also the pair of 12 wheels are raised from the floor 30, occurs due to the fact that the vehicle 1 is raised as a whole.

The second wheel set 20, which includes a pair of 22 wheels with both wheels 23, is located on the floor 30 or the corresponding rail of the second rail set. This second rail is integrated in the floor 30 so that it is practically not visible in FIG. 1. This rail of the second rail set has the same shape as the rail 14 of the first rail set, that is, it can also be made in the form of a round rod and is likewise integrated in the floor 30. The rail of the second rail set extends across the rail 14 of the first rail set .

A pair of 22 wheels of the second wheel set 20 is connected to the vehicle 1 by a switching device 24, the switching device 24 being shown here only schematically and will be explained in more detail later. In this case, the switching device 24, of which only a part is shown here, is provided for raising and lowering the second wheel set 20. Moreover, shown in FIG. Part 1 is provided for raising and lowering the pair of 22 wheels of the second wheel set 20. In this case, the raising and lowering of the second wheel set is carried out in such a way, in particular by such an appropriate force that, when lowering the second wheel set 20, the entire remaining vehicle 1 rises. FIG. . 1 shows this elevated position of the vehicle 1. In this situation, the vehicle 1 can move in the transverse direction, namely, across the longitudinal axis of the rotor blade to be manufactured, and thus approximately parallel to the plane of the drawing of FIG. 1. In particular, the vehicle 1 can be moved towards the hinge device 50 in such a way that it can be fixed between the movable arm 54 and the mold holder 2 by means of the fastening elements 58 by means of a hydraulic lifting device which raises and lowers at least least holder 2 forms. This hydraulic device may be part of vehicle 1.

In this case, FIG. 1 shows a portion of a manipulation device 60 that includes a vehicle 1, a first rail kit, including a rail 14, and a second rail kit, the first and second rail kit being at least partially embedded in the floor 30.

In FIG. 2, vehicle 1 is shown schematically, but in full, in a plan view. In this case, for clarity, the bidirectional arrow shows the longitudinal direction 11 and likewise the bidirectional arrow, the transverse direction 21. The longitudinal direction 11 and the transverse direction 21 are substantially at right angles to each other. There is no strict dependence on the angle of 90 degrees between these two directions 11 and 21, however, they should not be parallel to each other.

In FIG. 2, it can be seen that sixteen partial switching devices 25 are provided which together form a switching device 24. With each partial switching device 25, a pair of 22 wheels of the second wheel set 20 is matched. In each case, two partial switching devices 25 together with the connecting beam 32 are fixed to the longitudinal beams 34. In this case, the lowering of all pairs of 22 wheels by means of partial switching devices 25 and thereby by the switching device 24 causes the vehicle 1 to be lifted, in particular above these longitudinal beams 34. Moreover, a plurality of transverse beams 36 are located on the longitudinal beams 34, and accordingly native beams 34 and transverse beams 36 are combined with each other in a stable (frame) structure of the vehicle 1. Additionally, various longitudinally arranged support beams 38 are provided. Longitudinal beams 34, transverse beams 36 and support beams 38, which in each case are not must be identical, despite the fact that here in each case only one reference position is used for them, essentially form a vehicle 1, at least its stable supporting structure.

To drive the pair of wheels 22 of the second wheel set 20, several transverse drives 26 are provided, which additionally have a transmission mechanism 28. The connection to the corresponding pair of wheels 22 cannot be seen in the overview image of FIG. 2. Moreover, the transverse drives 26 in each case are mechanically independent from each other transmission mechanisms, which are however electrically connected or synchronized, so that when moving in the transverse direction 21 to achieve the most uniform and equal movement of the vehicle 1. At the same time not all pairs of 22 wheels of the second wheel set 20 are driven.

The pairs of 12 wheels of the first wheel set 10 are below the longitudinal beams 34, and therefore in FIG. 2 they cannot be seen, however in FIG. 3, at least in part, they are depicted in several places. To drive at least some of the pairs of 12 wheels of the first wheel set 10, a common drive is provided that mechanically transfers drive energy or drive moments through the shafts. These shafts are located or held essentially under the beams, namely, in particular, under the longitudinal beams 34, and can also be deflected by means of cardan shafts or otherwise.

In addition, a hydraulic unit 40 is provided, which is provided for actuating the switching device 24 and thereby the individual partial switching devices 25.

FIG. 4 shows in a front view of the vehicle 1 a view in the longitudinal direction of the vehicle 1. That is, the longitudinal direction extends here into the plane of the drawing. In the image, you can see two pairs of 12 wheels of the first wheel set 10 and two pairs of 22 wheels of the second wheel set 20. The movement of the shown pairs of 12 wheels is achieved using the distribution gear 42, which, in essence, works as a differential mechanism and in each case transmits the drive torque to the drive shafts 16, so that the corresponding drive torque reaches the corresponding pair of 12 wheels. In addition, cardan joints 18 are provided for deflection.

In this case, the cam gear 42 receives torque from the central drive through the corresponding drive shaft.

To align and / or register the position of the vehicle 1 in the transverse direction, vehicle indexing devices 44 are provided. These vehicle indexing devices 44 are fixedly located on the floor and can determine the position of the vehicle 1. In addition, the vehicle indexing devices 44 can hold the vehicle 1 on the floor 30 if the mold holder 2 is rotated from the vehicle 1 to the second mold holder 2 ' .

On the vehicle 1 there are lateral shear elements 46 which have connecting arms 48 so that the trellis truss or mold holder 2, which is shown in FIG. 1, thereby capturing and securing in many places. The lateral shear elements 46 are fixed to the transverse beams 36 by means of pins, fingers or the like, however, they can be disconnected from there and, in particular, change their position relative to the vehicle 1. As a result, they can adapt to changes, such as, for example, a change in the supported holder a shape or trellis and / or a change in the shape of the rotor blade.

Details of the vehicle indexing device 44 are shown in FIG. 5. In this case, the vehicle indexing device 44 has an indexing pin 62, which in turn has a conical head 64. The corresponding indexing receiving element 66 is adapted to this conical head 64 on the vehicle 1 with a corresponding recess 68, which approximately corresponds to a tapering blind hole. In this case, the indexing pin 62 can be inserted into this recess 68 of the indexing receiving element 66, and if it is fully inserted, the exact position of at least the indexing receiving element 66 is determined. Thus, if such indexing is performed in several places, namely, at least in both shown in FIG. 4 places that have the vehicle indexing device 44, the exact position of the vehicle 1 can be determined. In this case, the rest of FIG. 5 shows a fragment of FIG. 4, which is indicated there by a circle around the vehicle indexing device 44.

FIG. 6 shows a fragment of a vehicle 1 and a fragment of a longitudinal beam 34, on which a pair of 12 wheels of the first wheel set 10 is fixed and a partial switching device 25 of the switching device 24 is fixed. A pair of 22 wheels of the second wheel set 20 is fixed to this partial switching device 25 and is depicted in the lowered position. Schematically, without a floor image, the rail 14 of the first rail system and the rail 27 of the second rail system are shown. In this case, a pair of 22 wheels of the second wheel set 20 is located on the rail 27 of the second rail system.

In addition, FIG. 6 shows a transverse drive 26 which, by means of a transmission mechanism 28, reduces its rotational speed and accordingly increases the torque. Then, from the transmission mechanism 28, the driving moment through the drive shaft 16 is supplied to a pair of 22 wheels. From a functional point of view, drive shafts 16 that are connected to a pair of 12 wheels of the first wheel set 10, and those drive shafts 16 that are connected to a pair of 22 wheels of the second wheel set 20, are at least identical or similar, so one is selected for them the same reference position in order to emphasize their functional similarity. When transmitting drive torque to a pair of 22 wheels of the second wheel set 20, cardan joints 18 are also provided.

From the partial switching device 25, the lever-knee mechanism 70 can be seen. The lever-knee mechanism 70 has a crank hinge 72, as well as an upper and lower mounting hinge 74 and, respectively, 76. The crank hinge 72 is rotatably connected to the upper mounting hinge 78 by a hinge 74, and by means of a lower shelf 80 with a lower mounting hinge 76. A hydraulic actuator 82 is provided for actuating the lever-knee mechanism 70, which in FIG. 6 is mostly closed, and which acts directly on the articulated joint 72.

As shown in FIG. In the 6th position, the hydraulic actuator 82 is so extended that it moves the articulated joint 72 to a position in which the linkage mechanism 70 is straightened. Thus, the upper shelf 78 and the lower shelf 80 are located essentially on the same line.

In addition, you can see that a pair of 22 wheels of the second wheel set 20 is fixed on the pivot arm 84. In this case, the pivot arm 84 is secured to the partial switching device 25 with the possibility of rotation about the axis 86 of the pivot arm. In turn, a pair of 22 wheels of the second wheel set 20 is mounted rotatably on the pivot arm 84, namely, in the region of the fixing axis 88. Thus, the lever-knee mechanism first acts on the pivot lever 84, which can be rotated by the lever-knee mechanism 70, and the angle of rotation is very small.

In order to raise the pivot arm 84 and, together with it, a pair of wheels 22, and to thereby lower the vehicle 1, the hydraulic drive 82 draws the articulated joint 72 towards itself, as a result of which the upper and lower mounting joints 74, 76 move towards each other . As a result of this, the pivot arm 84 partially rises and therefore also raises a pair of 22 wheels of the second wheel set 20.

With this attractive movement, the linkage mechanism has a relatively small force. However, since, due to this movement, the vehicle 1 is lowered, this lever-knee mechanism also does not need an effort, at least a pulling force, when lowering the vehicle 1. In any case, it would be necessary to counteract the too rapid lowering of the vehicle 1. Only if the vehicle is lowered so that a pair of 12 wheels is located on the rail 14 and thereby the entire first wheel set 10 is located on the first rail set, a pair 22 wheels of the second wheel set 20 should be raised due to the continued movement of the lever-knee mechanism 70, for which, however, a relatively small effort is required.

The greatest effort is required when raising the vehicle, and here the effect of the lever-knee mechanism 70 is best manifested, which achieves a very strong lever effect. In addition, the vehicle 1 in the raised position, which is shown in FIG. 6 can be held almost effortlessly by means of a hydraulic actuator 82, since in this position the linkage mechanism is straightened.

The principle of operation of the linkage mechanism 70 is also explained in FIG. 7 and 8, in which FIG. 7 shows the elevated position of the pair of wheels 22 of the second set of wheels 20, and FIG. 8 shows the lowered position of the pair of 22 wheels of the second wheel set. In this case, FIG. 8 shows a position which is also shown in FIG. 6.

Moreover, in FIG. 7, it can be seen that a pair of 12 wheels of the first wheel set 10 with the wheel 13 is adjacent to the rail 14. A pair of 22 wheels of the second wheel set 20 is not in contact with the rail 27 of the second rail system. Thus, in FIG. 7, the vehicle 1 can be moved in the longitudinal direction, while in the position shown in FIG. 8 position creates conditions for movement in the transverse direction. For sequences of movements, reference is made to the explanation in connection with FIG. 6, which is likewise used here.
